A manatee is a peaceful, slow-moving sea creature that's often called a "sea cow." Manatees graze on ocean plants in marshy, shallow areas.

You may have to travel a bit to see a manatee — you can find them in coastal areas of the Caribbean Sea, the Amazon basin, and the West Indies, as well as a few rivers in Africa. Manatees are known for their gentleness and curiosity, which sometimes puts them at risk of harm, like when they get dangerously close to ship propellers and fishing nets. Unfortunately, humans are the main cause of death for young, healthy manatees.
